Description

Bending forming machine hydraulic pressure discharging winch

(1) technical field:

The utility model relates to the metal forming machinery in the mechanical engineering, specifically is a kind of bending forming machine hydraulic pressure discharging winch.

(2) background technology:

What the drawing mechanism of bending forming machine bending workpieces adapted mainly adopted at present is: the edger roll of configuration symmetry on feed appliance and the frame side before and after make-up machine, and what this discharge method adopted is the frictional force transmission, the driving force that can provide is very limited; The model specification for the treatment of out steel pipe on the other hand often changes, the steel pipe of same model is because the error that produces during moulding also may cause appearance and size to be not quite similar, the relative position that edger roll is managed material relatively when making each discharging is always changing, this brings very big difficulty for the automatic control of discharging, in addition, this discharge method efficient is very low, is difficult to adapt to the existing market pursuit more and more higher to efficient.

(3) summary of the invention:

The purpose of this utility model just provide a kind of efficient higher, be more convenient for controlling and the more bending forming machine hydraulic pressure discharging winch of large driving force can be provided.

Concrete scheme of the present utility model is: bending forming machine hydraulic pressure discharging winch, has workbench, counterdie is housed on the workbench, it is characterized in that: described lower die face is provided with one and goes out trolley, the lower die face both side edges is the groove shape, the dolly two bottom sides is equipped with directive wheel, and described directive wheel rides on the above-mentioned groove and can slide along its front and back; Little roof is equipped with cover rope sheave and rope processing device, and cover rope sheave wheel shaft is vertical with little roof; The support that one top has dual-cavity also is housed respectively on the workbench at described counterdie two ends, and the groove of groove on this support and aforementioned counterdie both side edges is on the same straight line; Along left side guiding train and the right guiding train that is made of some directive wheels is housed respectively on the face of the workbench left and right sides, a side is provided with hydraulic wireline winch therein; Described go out between trolley and the hydraulic wireline winch be placed on the cover rope sheave of dolly top with the steel wire rope stage casing, two strand steel wire ropes twine after a few through other side guiding train and support and lower die face groove along lower die face and a side stand groove, side guiding train to hydraulic wireline winch respectively again and enter little roof, and steel wire rope two ends are fixed in rope processing device and constitute closed loop and connect.

The course of work of the present utility model is: be placed on counterdie and eject on the roller on the oil cylinder after bending forming machine is bent into steel pipe with plate, go out on the dolly initial bit that trolley rests in a side, start hydraulic wireline winch this moment, traction drive discharging dolly by steel wire rope moves to the steel pipe direction, to drive steel pipe after going out trolley to stick steel pipe travels forward together, enter follow-up station until steel pipe being released make-up machine, the hydraulic wireline winch backward rotation, dolly returns along former road and rests in again on the initial bit, repeats aforesaid operations during each discharging and gets final product.

The utility model compared with prior art, discharging efficient is higher, be more convenient for control, the driving force that provides is bigger.

Among the figure: the 1-workbench, the 2-counterdie, 3-goes out trolley, the 4-trolley idler wheels, 5-dolly directive wheel, 6-overlaps rope sheave, 7-rope processing device, 8-counterdie groove, 9-rack groove, 10-support, 11-left side guiding train, the right guiding of 12-train, 13-hydraulic wireline winch, 14-steel wire rope.

(5) specific embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, the utlity model has workbench 1, be fixed with counterdie 2 on workbench top, lower die face is provided with one and goes out trolley 3, go out the trolley bottom and have four rolling 4, two directive wheels 5 respectively are equipped with in both sides, and little roof is installed with two cover rope sheaves 6 and several rope processing devices 7 side by side, and the cover rope sheave is vertical with little roof; The lower die face both side edges is groove shape 8, and the directive wheel of dolly rides on this groove and can slide before and after this groove; Also be fixed with the support 10 that a top has dual-cavity 9 on the workbench at counterdie two ends respectively, this groove equates with counterdie both side edges groove height and is on the same straight line; Along left side guiding train 11 and the right guiding train 12 that is made of 4-8 directive wheel is housed respectively on the face of the workbench left and right sides, left surface is installed with 7 directive wheels from top to bottom side by side in the present embodiment, right flank is equipped with 4 directive wheels from top to bottom side by side altogether, on the machine tool basic of a left side guiding train bottommost hydraulic wireline winch 13 is housed; During specific design, can determine the quantity and the concrete installation site of directive wheel according to working environment and condition, the directive wheel of installation can be guaranteed smooth and easy the getting final product of steel wire rope operation.Describedly go out between trolley and the hydraulic wireline winch to walk around out two cover rope sheaves at trolley top after the doubling in the steel wire rope 14 minutes, two strands that extend out are wrapped on the hydraulic wireline winch respectively after leading train along the groove process left side on lower die face and the left side brackets, after twining a few on the hydraulic wireline winch again through the foot directive wheel of left side guiding train, right hand guide wheels system enters out trolley along right side support and counterdie groove again, two ropes are terminal to be fixed on out on the rope processing device at trolley top, guiding train formation closed loop is connected about going out to adopt between trolley and the hydraulic wireline winch steel cable by the workbench both sides like this, hydraulic wireline winch adopts motor to drive, thereby the traction of forward and reverse rotation of winch by steel wire rope drives out trolley or right moving linearly left, thereby reaches the purpose of discharging to follow-up station.
